Other than testing this player about a year and a half ago - I never picked it up again. I was trying to sell it, and decided to test it this morning. All files that I put on it when I first got it, sounded hollow - the way a busted speaker would sound. I formatted the player - used Media Monkey and WM Player to put three new files on it, all of which played superbly on my SONY.

First file - from WMP - had that hollow sound.
Second file from MM - All lead vocals cut out -
Third File from MM - just garbled sounding

All files were converted to mp3

Anyone know what this is about? I have firmware 3.03 on it. The player has not been dropped or otherwise abused. It has been in the original box most of the time - and all of the other functions are working fine.
